The interface assemblyis a device that is configured to implement an interface extension function. The rotation detection device, which is disposed inside the housing, is capable of following changes in positions and postures of the docking stationin different usage scenarios.

The rotation of the docking stationmay cause a change in spatial position. The rotation detection devicedetects this change, obtains the rotation state parameter, and sends the rotation state parameter to the processing device.

The processing deviceis further electrically connected to the display device. During using the docking stationby the user, in a case where the spatial position of the docking stationchanges by rotating the docking stationrelative to a previous time period or moment, this change can be detected by the rotation detection device. In this case, the rotation detection devicecollects the rotation state parameter related to the rotation of the docking station, and sends the rotation state parameter to the processing device. After receiving the rotation state parameter, the processing deviceanalyzes to obtain the display adjustment signal. The display adjustment signal is a signal that is configured to adjust the display content of the display devicein a case where the docking stationis in a rotated state, making it easier for the user to view the display content. Finally, the display deviceadjusts the display angle of its display content according to the rotation angle of the display content carried by the display adjustment signal. Therefore, during using the docking stationby the user in multiple scenarios, the display content on the docking stationcan adapt to common observation habits of people, facilitating the user viewing the display content. Through this solution, in a case where the user rotates the docking stationfrom multiple angles during using the docking station, the display content on the docking stationcan adapt to real-time changes caused by the rotation of the docking station, thereby effectively improving convenience of information viewing during using the docking station.

1 2 3 4 5 10 1 2 3 4 5 1 2 3 4 5 30 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 30 40 In some embodiments, the accelerometer is also known as an acceleration sensor. The accelerometer is configured in the docking station,,,,(in some embodiments, the accelerometer is disposed inside the housing), so that acceleration changes in three dimensions can be detected in a case where the docking station,,,,is rotated.

The gyroscope can detect changes in an angular velocity of the docking station,,,,in real-time. That is, the gyroscope can detect rotational motion of the docking station,,,,. The gyroscope provides data (i.e., the rotation state parameters) on rotation direction and speed of the docking station,,,,, so that the processing deviceperforms display adjustment analysis for the display device.

20 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 40 In the actual scenario, the accelerometer or the gyroscope may be disposed individually as the rotation detection deviceto detect the rotation of the docking station,,,,, which can effectively reduce hardware costs.

20 In some embodiments, the rotation detection deviceis an inertial measurement assembly.

10 20 In some embodiments, the inertial measurement assembly is a measurement device that integrates or includes the accelerometer and the gyroscope.

t t wherein theta represents the posture change parameter (which may be an angle parameter) that is obtained after performing the complementary filter algorithm; alpha represents the complementary filter coefficient, typically ranging from 0 to 1, configured to balance weights of the gyroscope and the accelerometer; * represents multiplication; w represents the angular velocity measured by the gyroscope; Δt represents the time step; and theta_acc represents an angle derived from data of the accelerometer after unit conversion using an arctangent function. theta=alpha*(theta+ω*Δ)*Δ)+(1−alpha)*theta_acc,

30 40 40 Finally, after obtaining the posture change parameter, the processing deviceconverts the posture change parameter into a display direction angle, and sends the display direction angle to the display devicethrough the display adjustment signal carrying the display direction angle, thereby enabling the display deviceto adjust the display direction.

In order to facilitate understanding of the technical solutions of the present disclosure, the following explanation will be provided in conjunction with more detailed embodiments.

5 100 200 10 20 30 40 50 60 70 70 20 50 60 40 6 FIG. 7 FIG. 8 FIG. In some embodiments, the docking stationincludes the circuit substrate, the interface assembly, the housing, the rotation detection device, the processing device, the display device, the first communication device, the second communication device, and the low-dropout regulator. The low-dropout regulatoris a 3.3V regulator, and its specific structure may be illustrated in. The rotation detection deviceis the inertial measurement assembly (taking MPU-6050 as an example), and its specific structure may be illustrated in. The first communication deviceis the IIC communication module, and its specific structure may be illustrated in. The second communication deviceis the SPI communication module, and the display deviceis the LCD.

20 30 The rotation detection devicecommunicates with the processing devicethrough the IIC interface (SDA, SCL) to provide real-time acceleration data and angular velocity data (i.e. the rotation state parameters). The 3.3V LDO provides operating voltage to MPU-6050. VCC and GND are connected to a 5V power supply and ground, respectively. SCL and SDA, as well as XCL and the XDA, are two IIC communication buses, respectively. ADO is a slave address setting pin of the IIC communication module, and INT is an interrupt output pin.

4 5 30 In this way, during using the docking station,, the processing devicefirst initializes the MPU-6050 and SPI communication modules. After successful initialization, the required initial parameter and the complementary filter coefficient alpha for operation are configured. MPU-6050 performs data collection, obtaining the acceleration data from the accelerometer and the angular velocity data (i.e. the rotation state parameter) from the gyroscope. It determines whether the data is successfully received. In some embodiments, determining whether the data is successfully received can be achieved by determining the address and verifying whether the received data is within the preset numerical range.

30 40 After determining that the data is successfully received, the processing devicecalculates the time step Δ t and performs the integral calculation based on the acceleration data and the angular velocity data, to obtain the corresponding posture parameters. That is, the angle theta_acc is derived from the data of the accelerometer after unit conversion using the arctangent function. The angle theta_acc and the angle that is measured by the gyroscope are substituted into the formula theta=alpha*(theta+ω*Δt)+(1−alpha)*theta_acc for fusion analysis, to obtain the posture change parameter. The posture change parameter is converted into the rotation angle of the display content that needs to be adjusted by the display device.

30 40 40 40 4 5 Finally, the processing devicesends the rotation angle of the display content (carried by the display adjustment signal) to the display device, causing the display deviceto change the display direction. At the same time, MPU-6050 performs next data collection. Based on the data that is collected in real-time, it returns to the operation of determine whether the data is successful received. The analysis of the posture change parameter is repeated or continuously performed, so as to achieve real-time adjustment of the display direction of the display deviceuntil the docking station,is no longer in use.

Thus, the protection scope of the present disclosure should be subject to the contents of the claims.

In the docking station described above, the rotation detection device, which is electrically connected to the processing device, is disposed inside the housing. The processing device is further electrically connected to the display device. During using the docking station by the user, in a case where the spatial position of the docking station changes by rotating the docking station relative to a previous time period or moment, this change can be detected by the rotation detection device. In this case, the rotation detection device collects the rotation state parameter related to the rotation of the docking station, and sends the rotation state parameter to the processing device. After receiving the rotation state parameter, the processing device analyzes to obtain the display adjustment signal. The display adjustment signal is a signal that is configured to adjust the display content of the display device in a case where the docking station is in a rotated state, making it easier for the user to view the display content. Finally, the display device adjusts the display angle of its display content according to the rotation angle of the display content carried by the display adjustment signal. Therefore, during using the docking station by the user in multiple scenarios, the display content on the docking station can adapt to common observation habits of people, facilitating the user viewing the display content. Through this solution, in a case where the user rotates the docking station from multiple angles during using the docking station, the display content on the docking station can adapt to real-time changes caused by the rotation of the docking station, thereby effectively improving convenience of information viewing during using the docking station.
